Allow customizing Tenants DB JDBC uid/pwd/driver (FINERACT-806) (#713)

* Allow customizing Tenants DB JDBC uid/pwd/driver (FINERACT-806)

Added Java system properties for username and password to docker-compose

Modified sever.xml to get username and password

* Fixes for customizing Tenants DB JDBC uid/pwd/driver (FINERACT-806)

* Use random MYSQL_ROOT_PASSWORD in docker-compose.yml (FINERACT-806)

This provides future non-regression testing that the the customized
MySQL password is actually really used, and it doesn't just work because
"mysql" is still hard-coded anywhere.
